[0040] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0041] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0042] Embodiment 1:

[0043] This embodiment mainly describes the basic structure and working principle of a 360-degree circulation fan, specifically:

[0044] like Figure 1-Figure 3 As shown, the present application provides a high-efficiency and energy-saving 360-degree circulation fan, including a chassis 1, which serves as a supporting body of the circulation fan and is generally placed on a desktop or tabletop to support the entire circulation fan;

[0045] Meanwhile, the interior of the chassis 1 is hollow and forms a cavity (not shown in the figure), which is used to place the electrical components and accessories driving the circulation fan, and the chassis 1 is covered with an upper cover 2, so that the cavity is covered by the upper cover 2 to form a relatively closed space, so that the electrical components inside the cavity are protected;

[0046] A control panel 3 is provided on the upper cover 2, and a knob 31 and other control buttons are provided on the control panel 3 to control the operation of the circulation fan, wherein the knob 31 is a main control button, which mainly controls the opening and closing of the circulation fan;

[0047] Continue to refer Figure 1-Figure 3 A fan assembly is provided on the upper cover 2, and the fan assembly includes a rear cover 42 mounted on the upper cover 2. The shape of the rear cover 42 can be set according to actual needs and is not limited to a specific shape. As a preferred implementation of this embodiment, the rear cover 42 is spherical, ellipsoidal, or a spherical or ellipsoidal shape with a portion cut off. Optimally, in order to present the best swing effect, the rear cover 42 is hemispherical or hemispherical. As for the cross-section, it can be set to a plane, an arc surface or an irregular surface according to the use result or in order to pursue an aesthetic effect;

[0048] In this embodiment, the rear cover 42 is hemispherical, and the front cover 41 is installed on the hemispherical section. An accommodating space is formed between the front cover 41 and the rear cover 42, and a fan blade (not shown in the figure) is arranged inside the accommodating space.

[0049] It is understandable that the fan blades can rotate under the action of the rotating device to achieve the effect of air supply. Preferably, a wind net 411 is provided on the front cover 41 to guide the wind flow.

[0050] The rotating device includes a rotating motor mounted on the rear cover 42, and a fan shaft mounted on the output end of the rotating motor, the fan shaft is connected to the fan blades, so that the starting of the rotating motor drives the fan blades to rotate and supply air. In this embodiment, the rotating motor is arranged outside the rear cover 42, or arranged in the accommodation space. Optimally, the rotating motor and the fan shaft are both arranged in the accommodation space;

[0051] Furthermore, the fan shaft is arranged perpendicularly to the spherical center passing through the rear cover 42 and the section, and the fan blades are parallel to the section, so that vertical air supply can be formed;

[0052] like Figure 6-Figure 7 As shown, a connecting shaft 43 is mounted on the rear cover 42, and the connecting shaft 43 is suitable for rotating under driving, thereby driving the rear cover 42 to rotate synchronously;

[0053] The angle (defined as β) between the fan shaft and the connecting shaft 43 can be arbitrarily selected within the range of 0 to 90°, preferably, 10°<β<80°; preferably, 30°<β<60°, and most preferably, β is 45°;

[0054] It is understandable that the axis lines of the fan shaft and the connecting shaft 43 can be set in different planes, and a 360-degree three-dimensional swing effect can also be achieved. However, in order to make the circulation fan structure stable, or to seek structural or visual harmony, in the best embodiment, the axis lines of the fan shaft and the connecting shaft 43 are set in the same plane, and both pass through the spherical center of the rear cover 42;

[0055] In this embodiment, the circulation mechanism 4 is driven to rotate the connecting shaft 43, and the circulation mechanism 4 includes a fan seat 44, and the connecting shaft 43 is bearing-connected to the fan seat 44, so that the connecting shaft 43 is suitable for rotating on the fan seat 44;

[0056] At the same time, a first bracket 46 is connected to the bottom of the fan seat 44, and a motor 47 is fixedly installed on the first bracket 46. A first gear 48 is fixedly installed on the output end of the motor 47, and a second gear 49 is fixedly installed on the bottom of the connecting shaft 43. The second gear 49 meshes with the first gear 48, so that when the motor 47 is working, it can drive the connecting shaft 43 to rotate, and then drive the rear cover 42 to rotate synchronously;

[0057] It can be understood that when the rotating device and the circulation mechanism 4 are started, the first rotating device drives the fan blades to rotate on an axis perpendicular to the fan shaft, and at the same time the second rotating device drives the connecting shaft 43 to rotate, and drives the rear cover 42 to start rotating;

[0058] When the rear cover 42 rotates around the connecting shaft 43, the cross section of the rear cover 42 will rotate synchronously around the extended axis of the connecting shaft 43 and perform a 360-degree rotation in space, thereby achieving a 360-degree air supply effect.

[0059] Embodiment 2:

[0060] In the above embodiment, the fan seat 44 can be fixedly mounted on the upper end of the upper cover 2. Although this can make the circulation fan more stable, the air supply angle will still be limited. In order to make the air supply coverage area of ​​the circulation fan larger, the fan seat 44 is set to a structure with adjustable angle, specifically:

[0061] The fan seat 44 is arranged in the accommodation space, and the fan seat 44 can rotate. At the same time, a avoidance hole 21 is opened on the surface of the upper cover 2, so that the fan seat 44 can pass through the avoidance hole 21. In the initial state, the upper surface of the fan seat 44 is flush with the upper surface of the upper cover 2, and a sealing gasket is arranged at the position where the fan seat 44 and the upper cover 2 contact, so that the avoidance hole 21 can be closed. When the angle of the fan seat 44 needs to be adjusted, the fan seat 44 can be rotated a certain angle inside the avoidance hole 21;

[0062] It can be understood that at this time, the size of the avoidance hole 21 is slightly larger than the size of the fan seat 44, so that the fan seat 44 can have enough rotation space;

[0063] In this embodiment, an adjustment mechanism 5 is provided in the accommodating space, and the adjustment mechanism 5 is used to drive the fan seat 44 to rotate. Specifically:

[0064] like Figure 4-Figure 5 and Figure 8 As shown, the adjustment mechanism 5 includes a support portion 45 fixedly mounted at the bottom of the accommodating space, a second bracket 51 is fixedly mounted on one end of the support portion 45, an electric cylinder 52 is fixedly mounted on the second bracket 51, and the output end of the electric cylinder 52 is horizontally arranged;

[0065] At the same time, a slide rail 53 is fixedly installed on the support portion 45 at one side of the electric cylinder 52, and a first rack 54 is slidably installed on the slide rail 53. The first rack 54 is fixedly installed with the output end of the electric cylinder 52, so that when the electric cylinder 52 contracts, the first rack 54 can be driven to slide on the slide rail 53;

[0066] It can be understood that the operation of the electric cylinder 52 is mainly controlled by the button on the control panel 3. When the knob 31 turns on the circulation fan, the extension distance of the output end of the electric cylinder 52 can be adjusted as needed, thereby adjusting the movement distance of the first rack 54 on the slide rail 53;

[0067] Continue to refer Figure 5Two sets of bearing seats 56 are fixedly installed at the upper end of the support portion 45, and a rotating shaft 57 is rotatably installed on the two sets of bearing seats 56. A third gear 55 is fixedly installed at a position of the rotating shaft 57 close to the first rack 54. The third gear 55 and the first rack 54 are adapted to mesh with each other, so that when the first rack 54 slides on the slide rail 53, the third gear 55 can be driven to rotate by the meshing effect;

[0068] Meanwhile, two sets of rotating seats 58 are fixedly mounted on the rotating shaft 57, and the rotating seats 58 are provided with fixing pins 59. It can be understood that a pin hole is provided at the bottom of the fan seat 44, so that the fixing pin 59 can be inserted into the pin hole to connect the fan seat 44 and the rotating seat 58;

[0069] Therefore, when the electric cylinder 52 drives the third gear 55 to rotate, the rotating shaft 57 can be rotated synchronously, thereby driving the rotating seat 58 to rotate. As the rotating seat 58 rotates, the fan seat 44 rotates synchronously, so that the angle of the fan seat 44 changes;

[0070] The angle of the fan seat 44 changes, that is, the fan seat 44 is tilted, driving the rear cover 42 thereon to rotate, so that the circulation fan can be adjusted in angle, so that the circulation fan can rotate 360 ​​degrees at different tilt angles of the fan seat 44, thereby allowing the circulation fan to blow air without dead angles;

[0071] Preferably, the maximum adjustment angle of the fan seat 44 is 45 degrees. It can be understood that when the electric cylinder 52 is in the retracted state, the fan seat 44 is in a horizontal state. At this time, the fan seat 44 completely closes the avoidance hole 21 through the sealing gasket, making the circulation fan look more beautiful as a whole. At this time, this state can be defined as the storage state of the circulation fan.

[0072] When the cylinder is fully extended, the fan seat 44 rotates and tilts 45 degrees, and drives the circulation fan to rotate as a whole, so that the cross section of the rear cover 42 is in a vertical state. In this state, the axis of the fan blade is also in a vertical state. In this state, the circulation fan can realize horizontal air supply;

[0073] In this embodiment, the angle of the fan seat 44 can also be adjusted to any position between 0° and 45° to meet different air supply requirements.

[0074] Embodiment three:

[0075] In the implementation process of the above embodiment, the fan seat 44 rotates at the same height position, and although a certain angle can be adjusted, due to the limited thickness of the upper cover 2, when the fan seat 44 rotates too much, a part of it will be located at the lower end of the upper cover 2 and enter the accommodating space, which may affect the rotation of the rear cover 42.

[0076] In order to solve the above problem, in this embodiment, when the fan seat 44 rotates, the position of the fan seat 44 can be adjusted to a higher level, so as to avoid interference between the rear cover 42 and the upper cover 2 when the rear cover 42 rotates. Specifically:

[0077] In order to achieve the effect of raising the fan seat 44, a driving part can be fixedly installed on the rotating seat 58. The driving part is similar to the electric cylinder 52. The output end of the driving part is fixedly installed with the bottom of the fan seat 44. It should be noted that at this time, the fixing pin 59 can slide in the pin hole at the bottom of the fan seat 44. Because the fan seat 44 is raised a small distance, there is no risk of the fixing pin 59 slipping off.

[0078] Therefore, when the fan seat 44 rotates, the driving part is started at the same time, and the fan seat 44 is driven to move by the operation of the driving part, thereby achieving the purpose of raising the fan seat 44;

[0079] Because the above-mentioned scheme of raising the fan seat 44 requires the use of an additional drive unit, thereby increasing energy loss, it is better to Figure 8-Figure 10 As shown, a lifting mechanism 6 is provided on the support portion 45, and the lifting mechanism 6 can be controlled by the electric cylinder 52, so as to achieve the effect of solving the energy problem, specifically:

[0080] The lifting mechanism 6 includes a fourth gear 63 fixedly mounted on the rotating shaft 57, and the fourth gear 63 is located in the middle of the rotating shaft 57, so that the fourth gear 63 can rotate synchronously with the rotating shaft 57;

[0081] Meanwhile, the support portion 45 is fixedly mounted on the slide 61, and a second rack 62 is slidably mounted on the slide 61. The second rack 62 is vertically arranged and meshes with the fourth gear 63, so that when the fourth gear 63 rotates, the second rack 62 can be driven to slide vertically on the slide 61;

[0082] A hinge 64 is installed at the upper end of the second rack 62, and the other end of the hinge 64 is connected to the bottom of the fan seat 44, so that the second rack 62 and the fan seat 44 are hingedly connected through the hinge 64;

[0083] It can be understood that, in the initial state, the electric cylinder 52 is in a retracted state, the fan seat 44 is in a horizontal state, and the second rack 62 is in the bottom position;

[0084] When the angle of the fan seat 44 needs to be adjusted, the output end of the electric cylinder 52 is extended, so that the first rack 54 slides synchronously and drives the third gear 55 to rotate clockwise ( Figure 8 perspective), so that one end of the fan seat 44 is gradually lowered, so that the section of the rear cover 42 is gradually perpendicular to the horizontal plane, and the fan blades can rotate in the vertical plane;

[0085] When the third gear 55 rotates, it will drive the rotating shaft 57 to rotate synchronously, and then drive the fourth gear 63 to rotate synchronously. Due to the clockwise rotation of the fourth gear 63, the second rack 62 meshing therewith will be driven to slide vertically upward along the slide seat 61, and then the fan seat 44 will be lifted upward by the supporting method.

[0086] It should be noted that, by setting, the supporting speed of the second rack 62 can be greater than the rotation speed of one end of the fan seat 44, and since the second rack 62 is hinged to the fan seat 44, the distance difference caused by the speed difference will cause the second rack 62 to lift the fan seat 44 as a whole;

[0087] It should be noted here that the fixing pin 59 is slidably connected to the pin hole at the bottom of the fan seat 44, so the lifting mechanism 6 can be set at the center position of the fan seat 44, so that the lifting action of the second rack 62 can act evenly on the fan seat 44, thereby making the sliding of the fan seat 44 smoother.

[0088] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
